Table 32. FCU Outputs - Fields and Definitions.
Select the hardware version to be used for the controller. The different hardware versions have
different combinations of inputs and outputs. See the inset table below. The type of hardware you
select affects the choices that appear in the rest of the pages for FCU. Based on your hardware
selection, the configuration software ensures that you cannot configure a controller for an
application it cannot perform.

Define the type of fan coil unit that is being configured. It describes the number of pipes used on
the unit.
A fan coil unit that has only two pipes. This system type limits the controller to control only one
valve output and operate in a changeover mode. When operating in the changeover mode, the
controller uses only the one valve for controlling both heating and cooling. Use this configuration
only when changeover operation is required.
A fan coil unit that has four pipes connected, providing both heating and cooling at the same time.
The fan coil controller uses one output to control heating only and one output to control cooling
only, as configured in the control outputs (Equipment Control page).
Select the number of stages required for the fan output.
Select the use of the fourth relay for those controller types with four relays. This relay is normally
used for electric reheat, but can also be used for switching equipment not directly controlled by the
fan coil controller.
The relay is switched on when the control algorithm demands electrical reheat as defined in the
Reheat Options (Equipment Control tab).
The relay is switched on and off as commanded from the network. It is not controlled by the
internal fan coil controller temperature control algorithm.
